<em>1.</em> 35
<em>2. </em>45
<em>3. </em>45
<em>4. </em>65
<em>5. </em>115
<em>6. </em>65
<em>7. </em>80
<em>8. </em>35
<em>9. </em>145
3° and 177°
supplementary angles sum to 180°
let x be an angle then the other angle is 59x
x + 59x = 180
60x = 180 ( divide both sides by 60 )
x = 
= 3
the angles are 3° and (59 × 3 )= 177°
